With all the knowledgeable folks on the site can anyone provide the correct co ordinates of Rock Hill mine please? Its on the data base but is one of those that is shown as being near Edystone lighthouse in the Channel.
There does not appear to be a lot known about it although it is referred to by Collins as being a large open tin works (stockworks) in 1872, probably long since swallowed by a china clay pit.
Many thanks.

Have tweaked the GR to SX014582 a place called Rock Hill on the A391 between two china clay pits http://www.aditnow.co.uk/mines/ROCK-HILL-Mine/ , is this now correct (it was reading SX14582 previously) 🙂

Thanks for that Jimbo. That looks spot on.
Just found it in Dines tucked away in the description as part of the workings of the nearby Rocks & Treverbyn mine.
Looks like the Rock Hill stockwork swallowed today in the massive clay pit west of the road.

Even back in the mid-late 1970s most, if not all of the mine appeared to have been chewed up by the Rocks clay pit. I only had one trip down the pit around that time and did find a wide tourmaline quartz lode with fine grained cassiterite but I don't recall seeing any old workings in the pit walls.

As an aside, some of the filming for a BBC production called Stocker's Coppers about the clay miner's strike and the Welsh police that were bought in was shot very close to the Rocks pit in the early 70s.

I wonder if this is the same mine as "Rocks Mine" mentioned by HJ in Truro to the Clay District. I was pretty sure that Old Beam mine (fascinating HJ description) was opened up in the '60's via quarrying. I gather the shafts/workings were very closely timbered due to the crap rock. It sounds like the workings were sunk from the bottom of the clay pit for starters, the close timbering and dampness caused everything to rot and the air to be bad, they only worked it as it was so rich, but it ruined the health of the men. I gather Rocks Mine up the road (same position?) was pretty much the same thing. I gather stoping was open here and the same story about close timbering/etc.

I went for a look with my hammer and faaather and only managed to find a filled shaft (old beam). The blinking quarry was in operation, which thwarted my "looksee"

The 6" maps are hard work around there.

would that have been one of Ron Hooper's trips? I visited a clay pit in about 1976 to do some survey work with RH

Best I can ascertain, Rock Hill mine was opencast pit mine to west of road and now long been swallowed by vast clay pit.
Rocks mine is to the east of road and is separate working.

Interesting. I wonder if anything is there still.....?

1888 6" doesn't have Rocks/Rockhill mine on it.

1906 has Rocks Mine.

Dines doesn't mention Rockshill.

I give in, all too confusing for me.

Dines says Rock Hill (which is a circular opencast mine according to Collins) is 500 yds WSW of 4th milestone which ties in with the pit which shows on Stuey's post but is marked Rocks Tin Mine on the map. Dines also list seven different names for all these various jumbled workings.
Overall I just going to leave it as Rocks mine to cover the whole lot. Its all long gone anyway.

PS Just to add to the confusion, on the older maps Rock Hill china clay works is to west of road but on latest OS maps is shown as massive pit to east of road. How do you move a china clay pit?
Channel 5 Massive Movers have nothing on that one!!!

Thanks for all the inputs.

Mining Journal index database first reference 1836 Rocks Tin Mine, cross referenced to Good Luck Tin Bounds, Rocks Tin Mining Company, Rocks Consolidated Tin Mines, Rocks and Treverbyn United, Rocks and Carnsmerry, and of course your favourite and mine Rock Hill.
No hits after 1854, but can only reference up to 1860 at this time.

I don’t know if any use or just to further confuse.

My avatar is a poor likeness.

I am finding that map confusing.
From what i know, what is now known as carclaze pit started off as an open cast tin mine and was then turned in to a clay pit. It was often visited by gentry/wealthy types as it was the only open cast tin mine of its time.
May have something to do with the rocks work as on the map it could be the pit to the bottom. As for the roads question the road to the east of it is not very old.

hey Tomh we nowhere near carclaze pit on this thread, we up the road 2 or so miles at Goonbarrow.....or I thought we were.....really confused now.......going to go fishing instead !!!

Looking at the latest map from IMERYS survey section, Rocks pit and Tip and Wheal Henry are on east side of road, Goonbarrow pit and tip the other (west) side.
Rock Hill Tip seems to be on the west of the A391 in Goonbarrow pit eastern border where it borders the road. I suspect if it was an open cast mine, it got backfilled to form the tip if there was no clay present. Anyway it is all on the A391 between Stenalees and Bugle.
Rock Hill tip is at grid ref SX 011 581.

Is it safe to come out of the bunker yet?

There appears to be a shaft shown just below the highlighted Rock Hill China Clay Works on Stueys map, I wonder if that was it?

Also, there does not appear to be an entry for the Old Beam Mine whose workings/engine houses are in the top left corner on the same map, should this be added to the DB?

All very confusing 😉

Old Beam was aka Great Beam. I think it is on here.

The clay pit shaft could possibly be a slurry pumping shaft.

No, just me and Dad wandering around looking for cassiterite or whatever else came our way - Dad worked for ECLP so getting access in the early 70s was easy.

Across the main road we visited Goonbarrow pit many times, some of the old tin workings were spectacular, completely timbered walls, backs and floor in the clayey ground with lumps of turf/peat used to plug some of the cracks in the timbering. Some of the cassiterite they missed was quite excellent as well. Sadly no photos.

Did anyone get photos?

I think along with Hamilton Jenkin's quote about Old Beam, it would give a proper insight into the less glamourous of Cornish mines.

Here it is again, for the record.....

"The lodes in the Beam mine varied in width from a few inches to 6 feet but they were generally payable however narrow, owing to their being composed of almost pure cassiterite. The country rock, however was in many places so soft and porous that the men were put to the utmost shifts to prevent the sand courses and liquid clay from running in upon them. For this reason, the workings were kept as small as possible and heavily timbered, the lagging both in the shafts and levels being caulked with turves, furze and even grass. The timber frequently became loaded with fungus after it had been a short time in place, and the air throughout the mine was dead and heavy. "Nearly all who worked in Beam Mine suffered from miners consumption" the Parlimentary Commission was told in 1864. "They were all old men at the age of forty, but I should not call our miners old at that age. In fact, riding through the district, if you saw them you would say 'that is a beam man' "

A miner said:- "It was a bad air mine which killed scores of men, The mine was full of timber which eats the air, they could not work hard or long in the same place and often the candles would not burn unless placed at an angle to let the grease drip. He felt faint when underground, had headache, trembling of the limbs and could scarcely climb for weakness of the legs. "But we cannot always choose where we work when we want money".

I wonder if they would have opted for Benefits these days...

Spoke to someone at work who visited Rocks pit in the 1970's, apparently the workings extended under the road into Rocks pit. At the time he visited there were problems with the monitors washing part of a drive into the old mine. Timbers and candles etc were being washed into the clay stream causing lots of problems.

that may well be the origin of RH's trip, it is the sort of thing he would have concerned himself with in his consulting capacity
